BRACE SFOR AUTOMOBILE BDATRS.

Application filed 'uly 30, l1952i). Serial'No. 400,252.

To allwzomzt may comema- Be it known that l, MAX KnEcHArsKY, a citizen of theUnited l?ltates, and a resident of the city of Chicago, in the county of Cook and State of illinois, have invented certain new and useful lmprovements in Braces for Automobile Radiators, of which the fellowing is a full, clear, and exact specification. This invention relates to improvements in automobile radiator braces connecting the top and bottom tanks of the radiator, sup porting the casing, and, in turn, supported by side bars, usually of wood, to-which the braces and the casing are rigidly clamped by a screw-threaded nut Working on a bolt passing through the side bars and the flange of the brace and ofl the casing.

Heretofore, these brace bars or strips have each been formed from two pieces, provided with parallel opposing danges, spot-welded together, which flanges support the iianges oi'. the casing for the radiator, and are in turn supported by side bars, to which theV brace bars to ether with the casing are secured and rigidly clamped by means of bolts passing through the side bars, the flanges of the braces and the casing being tightened by a nut screw-threaded onthe bolt. The free ends of such braces are bent to conform to the opposing surfaces'of the tanks to which they are secured by rivets or bolts passing through the brace bars and the walls of the tanks.

Brace bars l'or automobile radiators, when constructed and secured itc-and connecting the tanks, as above to the objection that the vibrations of the running engine and the force from 'the jolts occurring to a traveling automobile are transmitted directly to the radiator and thereby constantly tend to not only openthe jointsr between the tanks and the radiator tubes, but to loosen the joints between the brace bars, their support, and the casing 'clamped thereto, with the result that the tanks are rendered inefficient because of not infrequent leakage; that objectionable rat! tlingl sounds are produced by `the radiator; that its durability is correspondingly reduced, and that the cost oi construction and installation of brace bars in two pieces is greater than need be for securing better results.

Another object of my invention is to have described, are subjec' a' brace bar for automobile radiators so constructed that the force of vibrations of the engine for, and the travelino automobile transmitted to the radiator Shall be substantially and materially reduced and to s. minimum, and the durability of the radiator accordingly increased and its greatest efficiency constantly maintained.

iith these ends in view, my invention finds embodiment in certain features oi novelty in the construction," combination and arrangement oi' parts, by which said objects and certain other lobjects are attained, all as hereinafter described with reierence to the accompanying drawings, Iand more particu lai-ly pointed out in the appended claims.`

ln said drawings- Fig. l is a side elevation olla brace for automobile radiators, in which my invertn tion nds its embodiment.

Fig. 2 is a similar view with the brace shown in its operative position for connectma* the tanks of the radiator.

"ig, 3 is a front elevation, partly in cross- -section, showing 'the side bars for support Fig. 5 is a 'side elevation of theradiator the samerparts in several figures of the `drawin s.

The racc bar of my invention finds its embodiment in a sin le bar 7, of bendable metal, of a width substantially that of the 'transverse diameter of the tanks 8 and 9 of the tube structure l0. of an automobile radiator, which strip is bent upon itself to torni an outwardly proiecting, ange il adapted to be projected across and be sup-- ported upon side bars 13 or through base support, and, in turn, support the flange 14 of the casing` l5 for a radiator, the opposing parallel faces of the erably, though not necessarily slightly but distinctly separated, as indicated' at 12, 1n order to impart greater resiliency to the fiange if and when desired forabsorption of the force of lvibrations otherwise iinparted to the radiator. l

The length of the brace bar? is suiciently flange being prefw top and bottom tanksthereof, and for which greater than that of the vertical sides ot the radiator' for its end to overlap in part the purpose thelower end of the bar, is pro'- vided with a bend 16, conforming to the contour of and adapted to partially overlap the opposing bottom` surface of the lower tank 9, its upper end being also provided with a bend 17 conforming to the, contour ot and havin overlapping con-l tact with the upper sur ace of the top tank and opposed thereto.

The top tank 8 may, as heretofore, have brazed thereto, adjacent 'the bend 17, a bracket 'plate 18 which, in its operative po sition supports the inwardly projecting; end 19 or" tbe upper tanl: 8.

The form ot ythe flange 11. by bending a singlepiece brace bar upon itself, not only furnishes a support for tbe radiator in its entirety from the side bars 13, but provides a means by which'tlie flange may be adapted' to yield to and absorb the force ot the vibrations of the engine and the automobile when running over rough roads,I heretofore directly transmitted to 'the radiator, and objectionable Jfor reasons before pointed out. In other Words, formed as are the brace bars of my invention from a single strip or bar of flexible iron or' steel, a yielding cushion is located between the side bars 13 and the radiator, due to the resiliency of the metal from which the bars are formed, maintaining the space between the arms forming the flange 11, following the tightening of the bolt 13'nl sufficiently to connect the radiator With and in its operative position upon the side bars 13. To this it may "be added that the resiliency of the arrn'of tbe U-shaped bend .forming the ange for the braces tends to lock the nut against accidental movement in its tightened position4 uponthe bolt. y

In addition to the advantages attributable to the construction'of a brace bar ot luy invention, as hereinbefore described, tbe pio vision ismade by which suilicientsolder may be introduced between the 4opposing'surfaces of a brace bar and the tanlslsfdr maintaining their adherence thereto against acciden tal detachment; 'i

To these ends, the bent and 17 oit" the brace bars adjacent are rospectiyjcly providedwith slots and .vhiclr, asshou'fn in the drawing, are elongated and are located transversely of the bars, but which may be of any other tornradapted to provide ducts through nhich 'n quantity oi' solder may be introduced between tire opposing surfaces of the brace bar and the surface of the tanks, which, `when siroated, will secure the brace bar and-tanks in their operative'position against accidental tie-- :folded upon itse 'strip separatelyto messes Having described my invention, wliat I claixn as new and desire to secure by Letters Patent is: ,l
